According to many scientists, quantum computers will have great importance in the future but, despite all efforts, research in this field is still in its infancy. One of the difficulties is understanding what criteria a quantum ...

Quantum photonics research could change the way we communicate, compute, and measure phenomena on the smallest scales possible. To probe these processes and design new technology that operates with single-photon ...

The laws of classical physics that describe the world around us can be very different from those of the quantum world. At the quantum level, particles can behave more like waves that can pass through each ...

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous ...

Ludwig Maximilian University of Munich researchers have uncovered a novel effect that, in principle, offers a means of stabilizing quantum systems against decoherence. The discovery could represent a major step forward for ...

Research into the strange phenomenon known as quantum entanglement - once described as 'spooky' by Albert Einstein - could revolutionise ICT over the coming years, enabling everything from ultra-fast computing ...

How does a classical temperature form in the quantum world? An experiment at the Vienna University of Technology has directly observed the emergence and the spreading of a temperature in a quantum system. ...

Researchers from the universities in Mainz, Frankfurt, Hamburg and Ulm have proposed a new platform for quantum simulation. In a theoretical paper recently published in Physical Review Letters, they show t ...

(Phys.org) —Some tasks that are impossible in classical systems can be realized in quantum systems. This fact is exemplified by a new protocol that highlights an important difference between classical and ...

(Phys.org) —Researchers at the Johns Hopkins University Applied Physics Laboratory (APL) have devised a quantum algorithm for solving big linear systems of equations. Furthermore, they say the algorithm could be used to ...

(Phys.org) —As one of the pillars of the natural sciences, thermodynamics plays an important role in all processes that involve heat, energy, and work. While the principles of thermodynamics can predict ...

(Phys.org) —Tom Wong, a graduate student in physics and David Meyer, professor of mathematics at the University of California, San Diego, have proposed a new algorithm for quantum computing, that will speed ...

In findings that could help overcome a major technological hurdle in the road toward smaller and more powerful electronics, an international research team involving University of Michigan engineering researchers, ...

(Phys.org) —In order to better understand how the laws governing the quantum and classical regimes are related to one another, physicists have performed an experiment allowing them to observe a quantum-to-classical ...
